Description
Technical field
The present invention relates to the critical components that equipment is irrigated in a kind of modern agricultural production, refer in particular to a kind of small-sized Precision Irrigation
The detachable rack of irrigation sprinkler.
Background technique
The advantages that spraying with its wide adaptability, being easy to do mechanization operation has become instantly most widely used section in the world
One of water irrigation technique.Extensive use has been obtained as the main irrigation equipment for realizing water-saving irrigation in irrigation sprinkler in recent years,
Mainly there are three kinds of giant sprinkler, reel sprinkling irrigation machine and middle-size and small-size irrigation sprinkler main types in China at present.Giant sprinkler is thrown
Money is high, and the device is complicated, and critical component relies on import, and is not suitable with China's topographic structure complicated and changeable and vast remote hills
Area；Reel type irrigator water turbine and transmission mechanism are inefficient, and intelligence degree is low to cause quality of sprinkler irrigation not high, are not suitable with
The development trend of water-saving agriculture；Small-sized irrigation sprinkler structure bulky currently on the market, mobile large labor intensity can not be fine
Popularization and use.In addition, sprinkling irrigation water distribution uniformity is to measure the important indicator of quality of sprinkler irrigation, it is spray irrigation system planning and designing
In important parameter.And the combination spacing and mounting height of spray head have a major impact sprinkling irrigation water distribution uniformity, still
Irrigation sprinkler spray head installation site currently on the market is relatively fixed, or mobile more difficult.Therefore, a kind of small-sized essence is invented
Standard irrigates the industry problems that the detachable rack of irrigation sprinkler moves sprinkling irrigation unit large labor intensity to alleviation, solves Different Crop, no
The distributing homogeneity of the technical problem and raising sprinkling uniformly sprayed with plot has a very important significance.
Through retrieving, currently without relevant document report.
Summary of the invention
The object of the present invention is to provide a kind of small-sized detachable racks of Precision Irrigation irrigation sprinkler, and it is multiple to can adapt to China
Miscellaneous topographic structure, at the same there is structure to be simple and convenient to operate, move conveniently, spraying efficiency is high, sprinkling uniformity is good, energy consumption
Low advantage.
